If you logged on with more than one account during the year, TurboTax may have sent you a notice that was referring to the account you did not end up filing your return with. Did you submit returns again without verifying whether your original returns were filed and accepted or not?
You could have verified their transmission and acceptance using this link: https://shop.turbotax.intuit.com/efile/efile_status_lookup.jsp
If the original returns were submitted and accepted, the returns you just filed today will be rejected.
If the original returns were submitted and accepted and you are getting a refund, you can check the status using the IRS tracking web site: https://www.irs.gov/refunds
